RADIATOR CONSTRUCTION.

Application filed June 14, 192,6. Serial No. 116,028.

This invention relates generally 'tof condensers designed `for-usein refrigerating apparatus yof the domestic type and consists ofv certain novel features` ofconstruction, combinations and arrangements of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure lis a side elevation of an apparatus embodying my invention; Y

Figure 2 is atop plan view thereof;

Figure 3 is a perspective view of a section of the coils;

Figure 4 vis a fragmentary perspective view of the supporting bracket.

In the drawings, a stand'is designatedat l upon which is mounted the usual refrigerating units, such as a pump,`rmo'tor, fan and radiator.A In the present instance, however, only the radiator is shown,l which is generally designated at 2, and consists of four laterally spaced vertically arranged coils A, B, C and D withthe convolutions thereof arranged in superposed relation..

These coils are supported'upon a common base, which in the present instance comprises a large tubeS anchoredin a suitable trough-shaped' recess 4e inthe stand. As shown the lowermost convolution of one of the intermediate coils is extended laterally as at l5' andvis connected in any suitable manner to the large tube 3, While the vuppermost convolution of one of the intermediate coils is extended laterally as at 6, forming an inlet passage in communication with Aany suitable pump (not shown).

The tube 3 serves as a reservoir for the condensed refrigerating medium aiitl is provided with an outlet opening (not shown) through whichthe fluid may pass to a brine tank.

To provide an efficient construction the tubing forming the radiatorhas a relatively small diameter, preferably three-sixteenths of an inch,r and is provided with a correspondingly Arestricted passage for therefrigerating medium.,VL y

Y With reference to the particular construction of the radiator, the vertically arranged coils A, B, C and Dare constructed of a f single length of tubing forming onecontinnous passage for the fluid from the inlet 6 to the outlet 5. As shown in Figure 3 all 'of the-convolutions in each horizontal plane are tangentially connected to each other as at 8 in such a mannerl that the refrigerant flows alternatelyy in,V a Y substantially horizontal plane fromone side-to the other, dropping down' to the n 'Xt lowest' plane' after it flows through each end convolution.

As shown in Figure 3 the tubing follows the convolutions in the end coils for a p0rtion 'of their length before continuing into the horizontal portions 8. Vertical supporting'brackets 9 extending from topy to bottom of the coils are mountecI upon the large tube 3 in any suitable manner and are providedV y With a plurality of grooves 10 which support the convolutions of the coils at diametrically opposite sides. Any suitable casing for enclosing the coils, such as the one shown at ll, may be provided if desired.

From the foregoing it will be apparent that an improved type of radiator has been provided which is very compactly arranged so as to accommodate a greater length of tubing` within a given space than has heretofore been possible with the ordinary type of radiators or'condensers. Such a construction has the advantage of increasing the radiating surfaces of the tubing in a given area, thereby providing a more efficient radiator.

While itis believedthat from the foregoing description, the nature and advantage of my invention will be readily apparent.

I desire to have it understood .that I donot limit myself to what is herein shown and described and that such changes may be resorted to when desired-as fall within the scope of what is claimed.

That I claim as my invention is:

' l. A radiator having a plurality of laterally spaced upright coils, all ofV the convolutions of each coil being tangentially connected to the corresponding convolutions of each adjacent coil lying in substantially the same horizontal plane.

2. A radiatorhaving a plurality of laterally spaced upright coils, the convolutions of each coil being tangentiallyconnected to the convolutions of each adjacent coil, the upate coils having a lateral extension forming an inlet passage and the lowermost convolution -of one of the intermediate coils having a lateral extension formingan outlet passa e. i

A radiator having a plurality of laterally spaced upright coils, the convolutions of permost convolution'of one of the intermedi- Y lio ezieh coil being Connected to the Convolntions oi euch adjacent eoil `at vertically spaced intervals, "hereln iinid passing through the said coils will travel alternately .in horizontal planes through .the coils `from one side oit' the radiator to the other.

l. A radiator having n plurality ot laterally Spneed upright Coils und substantially horizontal portions e.\:tending` amorose, the radiator ilroln one outside Coil to the other und connecting all the eonvolntions of each coil with the eonvolntions of ezieh adjacent coil, the tubing of the ontSide Coils following the eonvolntions thereof for a portion of their length :ind then connecting into the Said horizontal portions.

5. A radiator haring :1 `plurality ot laterally spaced upright coilS und substantially straight portions extendingl across the radi- :ttor from one outside coil to the other and (.onneotingmll o't' the convolntions of each coil with the eonvolntions of each horizon telly adjacent :eoih Said coils and Straight portions being formed of u single Continuons length of tubin".

In teetilnony whereof I allx my Siglfnxtnre.
